Question

sarah runs 1 hour each day,

Running burns .11 calories per min of body weight.

Nancy swims 2 hours a day and that burns .05c per min of body weight.

.11c 60

_____ X ______ X ?

1 min 1 hour

Answer 1

This is more of a math problem than a chemistry problem. Perhaps you should ask it again with a "math" tag.

Sarah runs 1 hour/day and burns 0.11 cal/min. To get calories burned/week, you have....

1 hour/day x 60 minutes/hour x 0.11 cal/minute x 7 days/week = 46 calories burned each week

Nancy swims 2 hours/day and burns 0.05 calories/min. To get calories burned/week, you have ...

2 hours/day x 60 minutes/hour x 0.05 cal/minute x 7 days/week = 42 calories burned each week.

So, since they weigh the same, you don't need to include weigh in the formula as it is a constant.

Sarah will burn more in a week than will Nancy.
